Methods and Means of Information-Analytical Assessment of Asteroid and Comet Hazard
This paper contains a description of methods and software tools for creation of the information-analytical system for monitoring hazardous space objects. The paper presents the structure of the system and a description of its functional components thet enable rapid assessment of the NEO hazard and forecast of the effects of dengerous celestial bodies colliding with the Earth. The results of the system's operation regarding the modeling the motion of spact objects are also included in this work.
The article suggests and describes a laboratory stand, allowing analysis printed board assembly electronic equipment (low-frequency amplifier) with the aim of monitoring the technical condition and diagnosis. This method has been implemented stand "Troubleshooting Handbook." The stand is designed for laboratory work by students in the course "means and methods of technical diagnostics."
Issues of ex post evaluation of mergers and antitrust bodies prescriptions are discussed. Among them: interrelation of enactment and enforcement from the perspectives of errors of I and II types in antitrust mergers control; probable consequences of mergers for competition; Аннотации к статьям 206 тьям № 1, 2012 comparative advantages and failures of decision variants available for antitrust bodies; ways of decision-making in expected merger. Also there are issues on efficacy of antimonopoly body decisions taking into account cost of monitoring, sanctioning of mergers participants, including influence on competition condition on relevant markets.
The notion that certain management practices at all levels create substantial competitive advantages for the company in the market received a lot of attention in the academic community over the years. A large body of work was accumulated as a result, though it appears that a comprehensive understanding of the relationship between management practices and firm performance is still lacking. This study is a part of a larger project aiming at closing this gap. The objective of this study was to create a typology of companies based on efficiency, using a number of objective criteria obtained from publicly available information.
The monograph concerned on the organizational problems of monitoring programs of innovative development at the biggest Russian companies. In the book there is an original methodical approach to managerial accounting, analysis and control of the progress and results of innovation at enterprises. Conception underlines features and level of development of corporate management technology and specific holding structures. Monitoring is considered as a function of strategic control in a large enterprise in the process of innovation.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
It is well-known that the class of sets that can be computed by polynomial size circuits is equal to the class of sets that are polynomial time reducible to a sparse set. It is widely believed, but unfortunately up to now unproven, that there are sets in EXPNP, or even in EXP that are not computable by polynomial size circuits and hence are not reducible to a sparse set. In this paper we study this question in a more restricted setting: what is the computational complexity of sparse sets that are selfreducible? It follows from earlier work of Lozano and Torán (in: Mathematical systems theory, 1991) that EXPNP does not have sparse selfreducible hard sets. We define a natural version of selfreduction, tree-selfreducibility, and show that NEXP does not have sparse tree-selfreducible hard sets. We also construct an oracle relative to which all of EXP is reducible to a sparse tree-selfreducible set. These lower bounds are corollaries of more general results about the computational complexity of sparse sets that are selfreducible, and can be interpreted as super-polynomial circuit lower bounds for NEXP.
The Handbook of CO₂ in Power Systems' objective is to include the state-of-the-art developments that occurred in power systems taking CO₂ emission into account. The book includes power systems operation modeling with CO₂ emissions considerations, CO₂ market mechanism modeling, CO₂ regulation policy modeling, carbon price forecasting, and carbon capture modeling. For each of the subjects, at least one article authored by a world specialist on the specific domain is included.
By using superconducting quantum interference device (SQUID) magnetometry, we investigated anisotropic high-field (H less than or similar to 7T) low-temperature (10 K) magnetization response of inhomogeneous nanoisland FeNi films grown by rf sputtering deposition on Sitall (TiO2) glass substrates. In the grown FeNi films, the FeNi layer nominal thickness varied from 0.6 to 2.5 nm, across the percolation transition at the d(c) similar or equal to 1.8 nm. We discovered that, beyond conventional spin-magnetism of Fe21Ni79 permalloy, the extracted out-of-plane magnetization response of the nanoisland FeNi films is not saturated in the range of investigated magnetic fields and exhibits paramagnetic-like behavior. We found that the anomalous out-of-plane magnetization response exhibits an escalating slope with increase in the nominal film thickness from 0.6 to 1.1 nm, however, it decreases with further increase in the film thickness, and then practically vanishes on approaching the FeNi film percolation threshold. At the same time, the in-plane response demonstrates saturation behavior above 1.5-2T, competing with anomalously large diamagnetic-like response, which becomes pronounced at high magnetic fields. It is possible that the supported-metal interaction leads to the creation of a thin charge-transfer (CT) layer and a Schottky barrier at the FeNi film/Sitall (TiO2) interface. Then, in the system with nanoscale circular domains, the observed anomalous paramagnetic-like magnetization response can be associated with a large orbital moment of the localized electrons. In addition, the inhomogeneous nanoisland FeNi films can possess spontaneous ordering of toroidal moments, which can be either of orbital or spin origin. The system with toroidal inhomogeneity can lead to anomalously strong diamagnetic-like response. The observed magnetization response is determined by the interplay between the paramagnetic-and diamagnetic-like contributions.
